Are you going to put a blanket over baby when he/she sleeps?

So I've been kind of paranoid lately thinking if I put a blanket on baby while he sleeps he will some way some how rap it around his neck, in terrified of this!! It rapping it around his face and suffocating himself. So I bought baby a swaddle me sack which is a wearable blanky!
So just curious, any moms feels the same way? Or any wise words to snap me out of this paranoia?! Am I just letting my head go crazy?
